Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a drill head structure,
particularly a drill head structure for dental handpiece which is
used in dental implant surgery for drilling a hole in an alveolar
bone in an affected area in the mouth.
[0003] 2. Description of Related Art
[0004] An artificial dental implant technology has been applied in
oral cavity treatment for years. Development in dental implant
materials and improvement in dental implant technology have
contributed to a greatly increased success rate of dental implant
surgery and have effectively solved problems with conventional
dental prostheses for patients with missing teeth. The foregoing
artificial dental implant surgery primarily involves placing an
implant body in an alveolar bone in an affected area in the mouth
to replace an extracted tooth root, attaching and securing the
implant body to an abutment, and fixing a crown to the abutment. An
artificial replacement is thus formed to replace a lost tooth.
[0005] In a conventional dental implant procedure, a drill head is
attached to a dental handpiece for drilling a hole in an alveolar
bone in an affected area in the mouth of the patient so that the
implant body may be placed and screwed into the alveolar bone.
Before the dentist starts drilling a hole, a position in the
affected area has to be planned for the hole. An optimal position
for the hole is usually a center between two teeth in the affected
area. For the time being, the position of the hole may only be
determined after inspection with the naked eye by an experienced
professional dentist. Further, the depth of the hole is determined
after evaluating factors such as the condition of the patient's
alveolar bone and the size of the implant body. An overdeep or
shallow hole will affect whether the implant body is successfully
and stably placed or not. Therefore, the dentist has to carefully
monitor drilling depth to facilitate placement of the implant
body.
[0006] With regard to the foregoing problems, drill heads which are
currently used in drilling holes in alveolar bones are of little
substantial help. They depend solely on the operation and control
of the dentists, and hence flaws may be caused by human errors and
remissness. Therefore, there is need for a novel and improved drill
head to solve the foregoing problems.
SUMMARY OF THE INVENTION
[0007] It is a primary purpose of the present invention to address
problems with dental bone drilling caused by design defects of
drill head structures. A drill head structure is provided in the
present invention which may be used for drilling a hole in an
alveolar bone, control the depth to which the drill head end goes
in, and assist in determining a precise position for drilling to
facilitate the placement of the implant body and improve its
steadiness.
[0008] A dental bone drill structure provided according to the
present invention comprises a drill head main body, a screw nut and
an adjusting ring. The drill head main body is a thin rod body with
an upper end that forms an attachment portion to be attached to a
driving end of a dental handpiece so that the drill head main body
may be driven by the dental handpiece to rotate at high speed. A
bottom end of the drill head main body forms a drilling portion for
drilling by cutting. In particular, above the drilling portion is
disposed a thread section. The screw nut is a hexagonal nut to be
screwed to the thread section of the drill head main body. The
adjustment ring has predetermined ring widths, and at a center
thereof is disposed a hexagonal screw nut indent for the screw nut
to be fitted into it. At a center of the adjustment ring is also
disposed a threaded hole to be screwed to the foregoing thread
section. The dental bone drill structure provided according to the
present invention may achieve the purpose of controlling the
drilling depth to which the drill head goes in and determine the
drilling position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] The technical content, features and effects of the present
invention will be fully demonstrated in the detailed description of
its preferred embodiment given herein below and the accompanying
drawings. It should be noted that the accompanying drawings are
illustrative and exemplary only and intended for the explanation of
a basic structure of the present invention. Therefore, it will be
appreciated that in the accompanying drawings only structures or
components that are relevant to the present invention are shown,
and the illustrated forms of structure, size, proportion, or number
of components are only one selective design.
[0016] The structure of the present invention and the effects it
may achieve are demonstrated below in conjunction with the
accompanying figures:
[0017] Please first refer to the three-dimensional exploded
structural drawing of a preferred embodiment according to the
present invention shown in FIG. 1, the three-dimensional assembly
structural drawing of a preferred embodiment according to the
present invention shown in FIG. 2, and the planar assembly
structural drawing of a preferred embodiment according to the
present invention shown in FIG. 3. As the figures show, the present
invention comprises a drill head main body 10, a screw nut 20 and
an adjusting ring 30, wherein:
[0018] The drill head main body 10 is a thin rod body with an upper
end that forms an attachment portion 11 and a bottom end that forms
a drilling portion 12, and above the drilling portion 12 is
disposed a thread section 13. The attachment portion 11 is to be
attached to a driving end of a dental handpiece so that the drill
head main body 10 may be driven by the dental handpiece to rotate
at high speed. The drilling portion 12 may drill by cutting.
[0019] The screw nut 20 is a hexagonal nut to be screwed to the
thread section 13 of the drill head main body 10.
[0020] The adjustment ring 30 has predetermined ring widths, and at
a center thereof is disposed a hexagonal screw nut indent 31 for
the screw nut 20 to be fitted into it. At a center of the
adjustment ring 30 is also disposed a threaded hole 32 to be
screwed to the thread section 13 of the drill head main body
10.
[0021] According to the component structure design of the foregoing
present invention, the attachment portion 11 is to be attached to a
driving end of a dental handpiece so that the drill head main body
10 may be driven by the dental handpiece to rotate at high speed
and the drilling portion 12 may drill a hole in an alveolar bone.
In particular, the screw nut 20 may be individually screwed to the
thread section 13 of the drill head main body 10, or the adjustment
ring 30 may be individually screwed to the thread section 13 of the
drill head main body 10, or the screw nut 20 may be placed in the
screw nut indent 31 of the adjustment ring 30 before being screwed
to the thread section 13 of the drill head main body 10. Please
also refer to the three-dimensional installation schematic view of
an adjusting ring according to the present invention illustrated in
FIGS. 4, 5 and 6. By screwing the screw nut 20 and the adjustment
ring 30 to the thread section 13 of the drill head main body 10 in
different manners, the drilling portion 12 may go into different
drilling depths. Further, the adjustment ring has predetermined
ring widths which correspond to the spacing between two teeth in
the affected area. There are various ring widths for the dentist to
choose from. Because the ring widths of the adjustment ring 30
correspond to the spacing between two teeth in the affected area,
during the drilling process the drill head main body 10 may be
limited by the spacing between two teeth in the affected area and
the drilling position may be as planned.
[0022] The structure design of the present invention achieves the
following advantages: [0023] 1. The adjustment ring 30 may be
screwed clockwise or counterclockwise so that its position on the
thread section 13 of the drill head main body 10 may be adjusted
and the drilling portion 12 exposed. This makes it easy for the
dentist to steadily control the drilling depth and prevent problems
of over or inadequate drilling. [0024] 2. The adjustment ring 30
has predetermined ring widths for the dentist to choose from, and
the ring widths of the adjustment ring 30 correspond to the spacing
between two teeth in the affected area. Therefore, during the
drilling process of the drill head main body 10, the adjustment
ring 30 may provide a guiding function for a drilling position so
that the drilling position may be as planned.
[0025] As the foregoing, the prevent invention primarily comprises
a drill head main body 10, a screw nut 20, and an adjustment ring
30. It may be attached to a dental handpiece for drilling a hole in
an alveolar bone, control the depth to which the drill head end
goes in the bone, and assist in guiding and determining a precise
position for drilling to facilitate the placement of the implant
body and improve its steadiness. However, it should be noted that
the structural content of the foregoing components is only
illustrated of a preferred embodiment of the present invention
rather than limiting of the present invention. It is intended to
cover various modifications and changes included within the spirit
and scope of the appended claims, the scope of which should be
accorded the broadest interpretation so as to encompass all such
modifications and similar structures.
